The DYNC2H1 gene provides instructions for making a protein that is part of a group (complex) of proteins called dynein-2. The dynein-2 complex is found in cell structures known as cilia. Cilia are microscopic, finger-like projections that stick out from the surface of cells. Dynein-2 is involved in a process called intraflagellar transport (IFT), by which materials are carried within cilia. Specifically, dynein-2 is a motor that uses energy from the molecule ATP to power the transport of materials from the tip of cilia to the base.
IFT is essential for the assembly and maintenance of cilia. These cell structures play central roles in many different chemical signaling pathways, including a series of reactions called the Sonic Hedgehog pathway. These pathways are important for the growth and division (proliferation) and maturation (differentiation) of cells. In particular, Sonic Hedgehog appears to be essential for the proliferation and differentiation of cells that ultimately give rise to cartilage and bone.
